"He claims to have learnt Koga Yamabushi Ninjutsu by a Senzo "Tiger" Tanaka. Er... googled the name of his teacher but couldn't find anything (apart from links to Bloodsport reviews and more articles of Dux). More BS, y'think?" Tiger Tanaka was a character in a James Bond movie. The character was the Head of the Japanese Secret Service. The film I think was "You only Live Twice" with Roger Moore playing 007.
